What is CVE-2023-53853?

A data race vulnerability in the Linux kernel's netlink implementation poses risks by allowing simultaneous read and write operations on the nlk->cb_running variable. The issue arises in functions netlink_recvmsg and netlink_native_seq_show, which access this variable without proper synchronization. This can lead to unexpected behavior and stability issues within kernel operations. Developers are urged to apply the latest patches that include READ_ONCE and WRITE_ONCE mechanisms to mitigate this vulnerability.
